This zipped file contains 2 Wordperfect files: The Preamble is 227KB, the Rule is 571KB. The Rule promulgates national emission standards for hazardous air pollutants (NESHAP) from existing and new plant sites that emit organic hazardous air pollutants (HAP) identified on the EPA's list of 189 HAP. The organic HAP are emitted during the manufacture of one or more of the following Group IV polymers and resins: acrylonitrile butadiene styrene resin (ABS), styrene acrylonitrile resin (SAN), methyl methacrylate acrylonitrile butadiene styrene resin (MABS), methyl methacrylate butadiene styrene resin (MBS), polystyrene resin, poly(ethylene terephthalate) resin (PET), and nitrile resin.
In the production of thermoplastics, a variety of organic HAP are used as monomers or are created as by-products. Some of these organic HAP are considered to be mutagens and carcinogens, and all can cause reversible or irreversible toxic effects following exposure. The potential toxic effects include eye, nose, throat, and skin irritation; liver and kidney toxicity, and neurotoxicity. These effects can range from mild to severe. The standards are estimated to reduce organic HAP emissions from existing affected sources by 3,550 megagrams per year (Mg/yr).
The intent of this rule is to protect the public by requiring the maximum degree of reduction in emissions of organic HAP from new and existing major sources. The emission reductions achieved by these standards, when combined with the emission reductions achieved by other similar standards, will achieve the primary goal of the Clean Air Act (Act) as amended in 1990.
